SY54017RMG

Analog Switches - Special Purpose Overview

The SY54017RMG is a fully differential, low voltage 1.2V/1.8V CML 2:1 multiplexer with fail-safe inputs. It processes clock signals up to 2.5GHz or data patterns up to 3.2Gbps. The device operates from a 2.5V ±5% core supply and a 1.8V or 1.2V ±5% output supply. It features guaranteed AC performance over the industrial temperature range of –40°C to +85°C. Key electrical parameters include a maximum propagation delay of 390ps (IN-to-Q), input-to-input skew under 20ps, and rise/fall times less than 95ps. The component is housed in a 16-pin MLF package.

Analog Switches - Special Purpose Feature Summary

• Ultra-low jitter design ensuring high signal integrity for high-speed applications
• Integrated fail-safe input circuitry that latches outputs during signal loss or low amplitude conditions
• Internal 3-pin input termination architecture supporting LVPECL, LVDS, or CML signals without external resistor networks

Analog Switches - Special Purpose Applications

• Data distribution for OC-48 and OC-48+FEC systems
• SONET clock and data distribution networks
• Fibre Channel clock and data distribution
• Gigabit Ethernet clock and data distribution

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix RMG corresponds to the MLF-16 package type and industrial operating range when sourcing components. Confirm lead finish specifications match system requirements, as the standard variant utilizes NiPdAu Pb-Free finishes. Ensure compatibility with existing PCB footprints designed for the 16-pin MLF form factor before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component for designs requiring high-speed CML signal routing with minimal jitter degradation. The dual-supply architecture allows independent optimization of core and output voltages. Verify that the selected VCCO setting aligns with the downstream receiver's input requirements, noting that termination strategies differ between 1.2V and 1.8V configurations.
